Two types of nephrons- cortical and juxtamedullary: - Answer✔✔-cortical- 85% loops of Henle
juxtamedullary- 15% with longer loops of Henle
Two major parts of the nephron: - Answer✔✔-Corpuscle: capillaries surrounded by a capsule
through which fluid is filtered out of the blood and into the nephron (glomerulus & Bowman's)
GFR!!!!
Tubules: where reabsorption of the filtered stuff is reabsorbed (99%)
GFR: - Answer✔✔-the rate at which fluid filters from the blood into the Bowman's capsule via
the corpuscle in the nephron
Bowman's Capsule: 3 layers - Answer✔✔-part of the corpuscle of the nephron also called a
filtration barrier/membrane. Layers:
1. glomerular capillary endothelium (pores)
2. basement membrane
3. visceral epithelium (sieve)
Process of filtrates passage through the nephron: - Answer✔✔-Blood enters the glomerulus -->
filtrate is formed and passes into the Bowman's capsule --> flows into the proximal tubule
(reabsorption)--> filtrate flows through the loops of Henle --> continuous recycling of Na
between filtrate --> filtrate enters the collecting tubules to become urine
